Do you give your dogs yak chews? They're made with yak milk and other ingredients.
They're really expensive, but they last a long time. At least the ones I've bought for my daughter's bulldog. The X-Large yak chew from the feed store costs $20 and will last her a week. She doesn't come over all the time, so it's a nice gift to give to her.
I haven't gotten it for my dog yet. But now that you have mentioned it, I think that it's not I should look into getting for him once in a while.
My dogs love yak chews. I think that they are even addicted to it because they know where I usually keep them and they always go to that place and bark at it. I'm being careful with giving it to them so that it doesn't have any side effects on them or affect their feeding.
If there's anything that I can afford to buy for my dog, I'm getting it for him. He's such a loyal pet. I always get him yak chews once in a while.
